New Guide updates is currently being worked on to better help everyone. Just taking longer than expected to finish.
*For those thinking about purchasing this game. Honestly. If you think you can do these tweaks then I say get it for a good sale price. If not then this is not the game for you and you should move on but you'll be missing out as it's really easy to do plus you have a great community that is willing to help you get it going. This is also one of the best co-op games made.*
*Remember to save often and save in multiple slots. In co-op both players should save at the same time. This means after doing a mission or buying an upgrade or making changes to your character or whatever. Make sure to save and again in multiple slots and never the same slot twice.*
If the game is not loading for you. Then check out IdolNinja's FAQ guide linked at the bottom of this post.
These tweaks can be needed to make the game functional and also add some awesome enhancements. :D
You may want to get Gentlemen of the Row: http://idolninja.com/sr2.php ****Does fix some issues & alters many aspects of the game from the vanilla version too. Read through the FAQ guide.****
*According to IdolNinja about choosing to use Gentlemen of the Row or not*
"The Gentlemen of the Row mod enhances the base game with additional content, and over 150 bugfixes and tweaks making Saints Row 2 a much more stable and rich experience. Some of the new content includes 100+ new clothing items with 120+ new logos, improved weather including a darker nighttime and more vibrant colors in daytime, plane and boat mechanics for customizing, additional missions, new vehicle dealerships, new weapons, new cribs, new homies and gang styles, more car paints, more skin colors, tattoos, makeup, optional 360/PS3 onscreen prompts, and even new cheat codes including NPC morphs (just to name a few.) All of these features have been extensively tested and confirmed to work correctly with either a new game and complete playthrough from start to finish, as well as being compatible with existing vanilla saves. Keep in mind certain new features aren't as slick as they could be. For example, the new vehicle stores have a naming problem when you buy them and it displays an strange name on the confirmation screen. Another example, is that Maero's monster truck can now be customized with everything except body paint. Doing so crashes the game, etc. I had to make a decision that the benefit of certain new features outweigh the problems with them.
While most of the Gentlemen of the Row mod is comprised of additions and enhancements, it also does permanently change some of the original features like certain taunts, compliments, walks, weapon meshes/skins, logos, and other things that may bother a purist."
Is everything going super fast in game? You have the CPU speedup bug. Easy fix. Just run Command prompt as Admin by right clicking on Command prompt and select run as administrator. Then copy and paste this without the quotes: "bcdedit /set useplatformclock true" then press enter. Now reboot and try the game. (If you have Powertools installed make sure to uninstall it first.)
From the guide linked below: "One reader reported that by just using the CMD (no BIOS editing), he was able to fix Saints Row 2's speed. So I suggest for those that don't want to edit their BIOS to just do it with CMD, see if it will work just by this way."
If you --wanna play co-op-- Use Evolve ( http://www.evolvehq.com ) as GameSpy is no more so the normal online mode will not work. With Evolve you can play LAN games online.
How it works:
One person creates a Party and the other joins. This creates a virtual lan. Leave the Party open or minimize it as closing it will disable the virtural lan. You can also set the Party to Private which is invite only for your Friends. ;)
Then one person hosts a Lan game and the other joins.
****You and your co-op partner will need to use the same options in GotR and any additional mods.****
If the other player trying to join cannot see the Hosts game then you may have the rare SR2 LAN issue some users have....This applies to straight up LAN or using an online LAN program like Evolve.
1. For the Host. Start Party in Evolve. Invite your co-op pal. Tell them to wait.
2. Go in the Network and Sharing center in Windows. On the left click on Change Adapter settings.
3. Now right click on your Network adapter not your Virtual Lan Adapter (Evolve Gaming Connection) and select disable.
4. Load up Saints Row 2 and host a LAN game it will say waiting for player. Leave it and Alt + Tab to the Desktop.
Re-able the network adapter you disabled. Now wait for the Evolve Party to reconnect.
4. Tell your co-op pal to go ahead join and Alt + Tab back in the game.
Should work. If it doesn't then you don't have UPNP enabled on your router and you will need to manually open a port on your router or enable UPNP. Check the Evolve Help section for more info.
Unfortunately until a real fix is discovered. The Host will have to do this each time when playing co-op. Again this seems to effect a small amount of people be it with virtual LAN or real LAN with Saints Row 2. Others it seems to work just fine and they don't have to do this at all.... Very strange.
